2.7.3 Preparing the Clone Tool Options
Before you start editing your image, take a look at the Tool Options for the
Clone Tool. As mentioned earlier, these settings can be accessed in the bottom
dock window of the Toolbox or by double-clicking the icon in the GIMP
The Clone Tool options are as follows:
• Mode : The Mode drop-down menu determines how the color is applied
to the image and what effect it will have. If you choose Normal mode,
color will be applied without elements being mixed or stacked from the
underlying image background.
• Opacity : Many paint tools offer the option of adjusting the opacity of
the color or pattern. The Clone Tool does too. The default setting is an
opacity of 100%. The application of the color initially is opaque, with the
exception of further features such as a fuzzy edge of the brush pointer
( Hardness ). In some cases, you may need to use a more glazing, semi-
opaque painting technique to achieve a desired result. For example, you
can set the opacity to 10% so that the color or structure will be applied
transparently, which means that the colors and structures underneath
that area will remain visible. Opacity allows you to apply a colored “glow”
as well as produce seamless transitions.
• Brush : You can access the Brushes selection window via this icon.
• Scale : The slide control lets you change the size of your paint brush.
• Brush Dynamics : First, you have to click the small button with the +
plus-symbol to expand the dialog to see the checkboxes for the Brush
Dynamics options. Choose your desired settings from the matrix Pressure ,
Velocity, Random and Opacity, Hardness, Size . You can change these
settings for your brushstroke even while working.
• Fade out : Similar to any other tool with a brush pointer, the Clone Tool
can be used to make wiping strokes that fade out. If you click the Fade out
check box to select it, the brush application will fade toward transparent.
You can also select the length of the feathering effect.
• Apply Jitter: Initiates a slightly jittery line that looks like its hand-drawn.
• Hard edge : Produces a hard, edgy result, even when you're using brushes
• Source : Use this option to select whether the information to be cloned
should be copied from the image ( Image ) or from a pattern in a palette
( Pattern ).
• Alignment : None means that a point in the image will be used as selection
area for application with the Clone. No matter where you apply the Clone,
the information will be taken from the same image point.
